Description

The utility model relates to the field of ensuring and controlling safe traffic and means of photo and video recording, it can be used to monitor compliance with traffic rules and safety at the intersection of railways and roads.

The prior art system for remote monitoring of the state of the railway track (RF patent No. 89055, IPC B61L 29/00, published on November 27, 2009), containing a video camera mounted on a support near the railway track, connected via a signal transmission means to the one installed in the control room information signal receiver. The system also includes a unit for registering the received information signal, an electronic unit for analyzing the information signal installed at the location of these cameras or in the control room with the possibility of analyzing the received image of the area of the danger zone with the detection of an object between the rails or the integrity of the rails and / or the railway embankment .

A similar system is known from patent RF 2313465, IPC B61L 29/00, publ. December 27, 2007).

A common drawback of these systems is the impossibility of objective monitoring of the observance by the drivers of vehicles of the traffic rules in the railway crossing zone, as well as the need to install expensive equipment on each locomotive for broadcasting a real-time video signal. In addition, these systems do not provide the ability to monitor the operability of the crossing signaling, as well as the recording of illegal actions of violators in relation to the means of objective control and crossing signaling.

A device for preventing emergencies at level crossings (RF patent 2284939, IPC B61L 29/00, publ. 10.10.2006), containing two video cameras placed on opposite sides of the railway crossing and connected to the control unit of the operation mode of the cameras, which in turn, it is connected with the control unit for the operation of the cross-country alarm system and with a signal transmitter of video cameras connected to a receiver installed in the premises of the station duty officer and on the rail vehicle, the output of which is connected to a computer Connected to the monitor and to the video recorder. The device also includes optical sensors associated with the unit for determining the average parameters of illumination and contrast, and a unit for recording and storing the reference signal, an obstacle detection unit is connected to the computer, which in turn is connected to monitors and an obstacle registration unit, which is connected to the executive control unit mechanisms in the room on duty at the station there is an obstacle separation unit connected to the computer and monitors and the emergency registration unit, the outputs of the latter connected to the control unit actuators and the transmission unit of information about the source of danger.

The disadvantage of this device is the inability to detect and record violations of traffic rules by road users crossing the railway crossing, including the automatic identification of vehicles that have become an obstacle to the movement of trains. The lack of the necessary evidence base obtained by means of objective control does not allow timely prosecution of traffic participants who intentionally violated traffic rules. And the latter, most often is the cause of dangerous situations in the railway crossing area. In addition, the disadvantage of this device is the need to install expensive equipment that includes a powerful transmitter and a broadband radio channel for transmitting a television image, as well as the lack of monitoring of the operability of the crossing signaling and recording of illegal actions of violators in relation to the means of objective control and crossing signaling.

Known electrical complex for preventing emergencies at level crossings (RF patent No. 94202, IPC B61L 29/00, published on 05/20/2010), containing video cameras mounted on opposite sides of the level crossing, train signaling control unit, train registration unit, a block for recording and storing a reference signal, a block for determining obstacle parameters, a block for analyzing the situation, a transmitter that transmits a control signal to the locomotive receiver, while the signal from the cameras is input to the signal processing block a, connected with the block for determining the parameters of the obstacle, the outputs of the blocks for registering the train and determining the parameters of the obstacle are connected with the block for analyzing situations, which in turn is connected with a signal transmitter to a locomotive connected via a radio channel to a receiver installed on the locomotive, which, in turn, is sequentially connected to the monitor and the emergency recording unit, and the cameras are located in such a way that not only the crossing itself is located in the field of visibility (intersection of the highway and jelly nodorozhnyh ways), but also the entrances to it that allows you to monitor and analyze the emergence of cars and other vehicles, is a potential cause of accidents.

The main disadvantages of this analogue are the impossibility of comprehensive safety monitoring at a railway crossing, the lack of identification of violators' vehicles, as well as the operability of crossing signaling devices.

The closest analogue, taken as a prototype, is a description of the Avtouragan hardware and software complex for video monitoring of level crossings (a page with a description of the complex: _files / 334/276 / h_cbcce13c314e44587c6326b89eb28658), which was developed by Recognition Technologies LLC. The complex includes two pairs of video cameras placed on opposite sides of the railway track, infrared searchlights and a computer for data processing. The complex receives signals from the traffic light controller and the barrier in order to determine the duration of the prohibition signal of the traffic light to record violations of traffic rules by drivers of vehicles crossing railway lines.

The disadvantage of this complex is not the best location for video cameras for fixing license plates of passing vehicles. With a similar arrangement of cameras, the number plate of the fixed vehicle can be blocked by vehicles moving in the opposite direction, which will inevitably lead to a decrease in the efficiency of the complex and the appearance of errors. In addition, the complex does not provide for the ability to control the operability of crossing signaling devices and other potential sources of danger.

The objective of the claimed utility model is to eliminate the shortcomings of existing analogues by creating a security monitoring system at a regulated railway crossing, which provides a timely effective set of measures to identify violations of traffic rules and potential sources of danger at the intersection of the railway track with highways.

The technical result is to increase the level of security in the areas of intersection of the railway track with roads, providing an objective evidence base in cases of violation of the rules of the road or dangerous situations created by road users or third parties in these areas, increasing the reliability and efficiency of objective monitoring and crossing Alarms combined with high performance and low cost.

The technical result and the task are achieved by the fact that the security monitoring system at a regulated railway crossing includes four video cameras located on both sides of the railway track and hardware and software that recognize the state registration marks of vehicles, with two installed on each side of the crossing video cameras, the first of which is located to the left of the road section adjacent to the crossing and is connected by a data transmission channel to the module fixing and recognition of state registration plates (ГРЗ) of vehicles (TS), and the second video camera is located to the right of the road section adjacent to the crossing, in front of the traffic light and is connected by a data transmission channel to the signal receiving module of the traffic light and barrier through the video and the intruder detection module, output the module for fixing and recognizing the vehicle’s GRZ is connected to the input of the module for monitoring the direction of movement of the vehicle, the output of which is connected to the input of the module for detecting obstacles on the tracks, the output of the module for receiving traffic signals the video barrier is connected to the input of the signaling health analysis module, which is configured to receive information from traffic light controllers, the barrier and the level crossing barrier (USP), the output of the traffic light signal and barrier module is connected to the input of the vehicle direction control module, the module outputs detection of obstacles on the tracks, the module for monitoring the direction of movement of the vehicle, the module for detecting intruders and the module for analyzing the health of the alarm are connected to the input of the registration module offenses and emergencies (PE).

Camcorders and an offense and emergency registration module are connected to the memory module. In addition, the output of the offense and emergency registration module is connected to the warning and communication module.

Video cameras are located on both sides of the railway track (see Fig. 1). In a preferred embodiment, the video cameras 1 intended for fixing the GRS TS are black and white, and the video cameras 2 (overview) are color with wide viewing angles. In a preferred embodiment, the video cameras are placed at a height of 5 to 8 meters above the ground on special supports or they are attached to existing supports, for example, power transmission towers or lighting poles.

As a rule, surveillance cameras 2 are placed at some distance from the railway track, so that a section of the road adjacent to the railway track, as well as means of crossing signaling, in particular a traffic light 3 and a barrier 4, fall into the zone of their visual inspection.

Surveillance cameras 2 are designed to collect evidence base that provides objective decision-making in relation to violators of the rules for crossing a railway crossing, as well as to verify decisions already made on the basis of a recorded record and testimony of a crossing signaling device at the time the violation was recorded. In addition, the video cameras 2 provide visual control of the operability of the means of crossing signaling, as well as the detection of intruders in the crossing zone. It is desirable that the video cameras 1 enter the visibility range of the survey cameras 2 (it is shown by the dashed line in Fig. 1).

Recognizing cameras 1 are located near the railway track and are directed towards the oncoming traffic stream from the crossing. This arrangement provides maximum visibility of license plates of vehicles moving towards them in the crossing zone.

In order to promptly inform about the emergency in the moving zone and take the necessary measures as soon as possible, the claimed system may contain voice communications between the station duty officer or the dispatcher and road users. These means of communication can be installed directly in the crossing zone or in the territory adjacent to it in the form of a communication terminal fixed on a vertical support and another terminal installed at the nearest station or in a control center.

The claimed system contains hardware and software that provide recognition of state registration marks (GRZ) of vehicles (TS) passing through the crossing. The indicated tools are implemented in the module for fixing and recognizing the GRZ TS based on an industrial computer. Structurally, a computer can be made either as a standalone device, or can be integrated into a single housing with one of the cameras.

An industrial computer can be installed in the railway crossing zone, in the room of the station duty officer or in the dispatch center. The preferred location for the computer is located directly in the railway crossing area or in the room of the station duty officer. This eliminates the need to transfer a large amount of information to remote centers, providing the processing of all data on the spot.

Important elements of the claimed system are the modules for processing and storing data received from video cameras, which can be implemented both at the software and at the hardware-software level based on the same industrial computer.

These modules include:

- module for fixing and recognition of state registration marks (GRZ) of vehicles (TS),

- module for controlling vehicle direction of movement,

- module for detecting obstacles on the tracks,

- module for detecting intruders,

- a module for receiving traffic signals and barriers for video,

- a module for analyzing the operability of cross-country signaling,

- module for registering offenses and emergencies (PE),

- notification and communication module,

- memory module.

Using these modules and video cameras, the claimed system allows you to solve a whole range of problems:

- monitoring and fixing of emergency situations on the tracks and in the railway crossing zone,

- monitoring the performance of signaling equipment at the crossing,

- control over the actions of potential attackers,

- fixation and prevention of traffic violations in the area of railway crossings.

The claimed system is illustrated in FIG. 1 and FIG. 2.

In FIG. 1 shows a diagram of the location of the cameras relative to the railway track and the signaling equipment of the crossing.

In FIG. 2 shows a block diagram of the main elements of the claimed system and their relationship with each other.

The module for fixing and recognizing the GRZ TS is intended for analyzing frames received from video cameras 1 (see Fig. 1), for identifying and recognizing the GRZ TS.

The vehicle direction control module provides an analysis of the sequence of frames received from cameras 1. As a result of this analysis, the direction of motion or the stationary position of each vehicle passing through the crossing is determined.

The module for detecting obstacles along the tracks is designed to detect emergencies that can lead to serious consequences. This module analyzes the information received from the video cameras 2 (see Fig. 1) for the presence on the paths of the object during the time interval exceeding the set value, or at the time of the prohibition signal of the traffic light. This module also receives information from the vehicle direction control module in those cases when it is established that a stationary vehicle is on the tracks.

The module for detecting intruders processes the information received from cameras 1 and 2 to identify facts of unlawful actions by unauthorized persons in relation to the means of objective control (cameras, industrial computer) and signaling equipment of the move.

The module for receiving a traffic signal and a barrier for video contains software for determining the signal of a traffic light 3 and a barrier 4 from video frames received from video cameras 2 (see Fig. 1).

The cross-country signaling health analysis module is designed to compare the data received from the traffic light and barrier signal receiving module via video with the signals received from the traffic light controllers 3, barrier 4 and УЗП 5 (level crossing devices).

The module for registering offenses and emergencies provides the analysis of all data received from other modules, the systematization and registration of all detected violations, malfunctions and emergencies, as well as the transfer of important information to the duty officer at the station or to the dispatch center.

The notification and communication module is a set of tools that ensure the exchange of information between system elements, as well as the transfer of important information from the offense registration module and emergency to the duty officer at the station and / or to the dispatch center. In addition, this module may include voice communications between road users and a station duty officer or operator in a dispatch center.

The memory module is a secure means of storing information received from video cameras and the module for registering offenses and state of emergency. As such tools can be used hard drives, solid state drives and other devices. The operation of such devices is controlled by special software.

A description of the operation of the claimed system is given below.

Before starting the system, the video cameras are installed and configured according to their purpose as shown in FIG. 1. After bringing the system to working condition, information from all cameras in automatic mode flows into the memory module. Later, it can be used as an additional evidence base in a detailed trial.

Information from the video cameras 1 enters the module for recording and recognition of the vehicle’s GRS, in which the number plates of the vehicle are identified on the received frames with the help of special software (software) and the identification of the vehicle’s GRZ is performed. Camcorders 1 form several frames of the same vehicle and its own GRZ.

After identifying the vehicle by the GRZ, information about it along with a set of frames of the number plate of this vehicle is transmitted further to the module for controlling the direction of movement of the vehicle. In this module, a comparative analysis of the direction of movement of the identified vehicle is carried out according to changes in the size and position of the GRZ plate in time relative to the roadway and video camera 1.

Since each of the video cameras 1 controls both lanes of the vehicle through the crossing, and also determines the lane of entry and the lane of exit, the situation when the GRZ TS approaches the video camera along the lane of entry and moves away from the camera along the exit lane is standard. If the abnormal direction of movement along the lane is detected, then a package of data on the offense (exit to the oncoming lane) is formed and sent to the module for registering offenses and state of emergency. In the event that the GRZ TS approaches camera 1, but at the same time the information on the operation of the prohibition signal of the cross-country signaling is received from the signal reception module of the traffic light and the barrier, a data packet of the offense is generated (travel to the prohibition signal of traffic light) and sent to the registration module offenses and state of emergency.

If a vehicle’s GRZ has been found in the danger zone for longer than a certain period of time (necessary to travel through the crossing), a data packet is generated in the direction control module and sent to the obstacle detection module on the tracks, in which a more detailed analysis of the situation is performed.

In the module for detecting obstacles on the paths, an analysis of frames coming from cameras 1, as well as a data packet from the module for monitoring the direction of movement of the vehicle. In the course of additional processing of information, the level of danger of the current situation and the need for sending an emergency data packet to the module for registering offenses and state of emergency are determined.

Simultaneously with the identification of the above violations and the state of emergency, the claimed system is able to identify and record the actions of intruders that could cause damage or disrupt the operation of crossing signaling equipment, as well as objective monitoring tools, which include the video cameras themselves.

For these purposes, information from video cameras 2 is transmitted to the intruder detection module. Special software detects any activity in the areas where the signaling equipment is installed, as well as video cameras and a computer (if it is installed directly in the moving zone). Depending on the needs, any control zones within the visibility of video cameras can be set. If the activity is determined within a certain period of time, an alarm signal is generated in the module for detecting intruders and, together with the actual evidence, is sent to the module for registering offenses and state of emergency.

For timely elimination of possible malfunctions in the operation of the signaling equipment of the relocation, the claimed system is equipped with autonomous diagnostics of the operability of signaling equipment. The video cameras 2 are installed in such a way that a traffic light 3, a barrier 4 and an ultrasonic protection device 5 (if equipped with a crossing) get into their visual control zone. Information from the video cameras 2 is processed in the traffic light and barrier signal receiving module by video, in which by comparing the frames from the video cameras 2 with the reference frames, the signal of the traffic light 3 and the barrier 4 at each moment of time is determined. This information is transmitted to the vehicle direction control module and to the signaling health analysis module.

The signaling health analysis module is configured to receive information directly from the controllers of the traffic light 3, barrier 4 and УЗП 5 (if any). By comparing the signals received from the signal receiving module of the traffic light 3 and the barrier 4 by video and the above controllers, the software of the signaling health analysis module carries out continuous diagnostics of the signaling equipment operability of the crossing. In case of detection of incorrect operation of signals from any of the crossing signaling elements or its failure, a packet of data on the emergency situation is sent to the module for registering violations and emergency situations.

Information on all detected violations, emergency situations and emergency situations is collected in the module for registering violations and emergency situations. This information is additionally analyzed, systematized and sent on-line to the control panel in the dispatch center and / or on-call duty of the nearest station. At the same time, this information is stored in the memory module.

The composition of the claimed system may additionally include voice (speakerphone) means between the station duty officer or dispatcher and road users. This allows not only to inform the relevant services on time of a possible danger, but also to report the cause of the incident or to ask for help.

Thus, the claimed system provides an integrated approach to security control at a regulated railway crossing. It allows you to identify and record the facts of violations on the part of drivers of vehicles (exit into the oncoming lane, travel to the prohibitory traffic signal). timely diagnose malfunctions in the signaling equipment of the crossing, detect and record illegal actions in relation to the signaling equipment and means of objective control of the railway crossing, as well as identify other potentially dangerous situations for traffic participants at the railway crossing.

It should be understood that the essence of the claimed system is manifested in the functional purpose of each of its elements, as well as in the scheme of interaction between them.
